This section applies in a case where—
the old assets that are disposed of are interests in UK land, and
a chargeable gain accruing on the disposal would (apart from section 152) be within the charge to tax because of section 1A(3)(b) or 2B(4)(a).

"interest in UK land" has the meaning given by section 1C,
"the old assets" and "the new assets" have the same meaning as in section 152,
any reference to a disposal of the old assets includes a disposal of an interest in them,
the reference to the acquisition of the new assets includes the acquisition of an interest in them or entering into an unconditional contract for their acquisition.
